Seasonic Focus GX-1000 V4 ATX v3.1 PSU Review

Box & Bundle

Strangely enough, the box doesn’t have a photo of the PSU on its front side. Only the model description and a mention of the ten-year warranty.

Product Photos

The PSU’s small dimensions and the unique design of the fan grille make an appealing combination. On the PSU’s front side, you will find the AC receptacle, the power switch, and another switch to toggle on/off the fan’s semi-passive operation. Around the back, the modular panel has eleven sockets, including a native 12V-2×6 one.

Cables

Modular Cables
Description Cable Count Connector Count (Total) Gauge In Cable Capacitors
ATX connector 20+4 pin (620mm) 1 1 16-18AWG No
4+4 pin EPS12V (610mm) 2 2 16AWG No
6+2 pin PCIe (750mm) 3 3 16-18AWG No
12+4 pin PCIe (750mm) (600W) 1 1 16-28AWG No
SATA (510mm+155mm+155mm+155mm) 2 8 18AWG No
SATA 3.3 (410mm+160mm) 1 2 18AWG No
4-pin Molex (450mm+125mm+125mm) 1 3 18AWG No

There are enough cables and connectors to handle the PSU’s max power without any issues, including two EPS, three PCIe 6+2 pins on dedicated cables, and a single 12V-2×6 cable with the PSU’s setting for 600W. According to Intel’s test plan, it should be at 450W, but most manufacturers go for full power on this cable. The EPS and PCIe connectors mostly use 16AWG gauges for lower voltage drops.

The number of peripheral connectors is sufficient, and the distance between the SATA connectors is adequate. On the contrary, the 4-pin Molex connectors are relatively close to each other.

  1. Thank you for the great review! I’m personally waiting for the ATX3.1 compliant Vertex PX-1200. But a sales rep from Seasonic told me those are currently only available in Asians markets at the time. Do you maybe have an estimate when the ATX3.1 versions of the Vertex series become available in the EU?
